sec X = 13/5. x lies in 4th quadrant. cos X = 1/ secx.
So, cos x = 5/13. sin X = √ 1- cos²x.
sin X = -12/13. ⚆As sin functions-ve in 4th quadrant. cosec X = 1/sin X.
cosec X = -13/12. ⚆As cosec functions-ve in 4th quadrant. ...
tan X = -12/5. ⚆As tan functions-ve in 4th quadrant. ...
Cot x = -5/12.
